Sample Analysis Facility provides a processing and a storage of various numerical data and a pre-processing and analysis of sea water samples, sea floor core and etc. from Oceanographic R/V “Mirai”. 　 　 Analysis building■ two-story reinforced concrete total space/1,943 Major facility■ Sea water pre-process lab., ICP-MS lab., Chemical experiment lab., Pigment Analysis lab., Data processing lab., Rocks processing lab. and Organisms breeding lab. 　 　 　 Sample Analysis Facility Seawater pre-processing system Inductively Coupled Plasma Mass-Spectrometer （ICP-MS） 　 　In order to measure radiocarbon in seawater by accelerator mass spectrometry, this system extracts carbon dioxide gas from seawater sample and converts the gas into graphite powder. The radiocarbon measurement gives “age” of seawater sample. 　This system performs high precision analysis for minor and trace elements in sea water, marine particles and sediments.
